BTW, I don't disagree with the notion that some gambling, and alcohol and cigarette (and Cash Converter) companies push their products to the less well-off.
Where I take isssue is when people think that banning these companies is the solution. It's certainly a great campaign slogan and an easy bandwagon for government and activists to jump on.
What it fails to address is the actual poverty and deprivation of the communities that are being targeted. That is a more important problem to address, and will take much more effort to solve. And governments (especially ones of the current shade of blue) aren't too interested in solving hard problems; especially when they can stay in power without those votes.
